Now, the RSP interpreter works just fine with Gauntlet Legends. Actually I've been having it on while completing a game save using the beta version but using the RSP re-compiler on the 1.6 version. Only issue is if I start the game using the RSP interpreter on 1.7 but then switch to the re-compiler, there is an endless streak of errors similar to this.

The [r4k] interpreter, though, is what I meant from before. Project64 1.6 starts Gauntlet Legends with the r4k interpreter or the re-compiler, but I've never succeeded in getting the r4k interpreter to initialize the game on the recent alpha. I haven't checked this on all the legacy beta versions.

Hard for me to comment on style and stuff, when it comes to software or design. My idea is to develop in such a way that there is minimal interface needed to apply stylistic measure to, in order to keep neutral or professional.
